Re: Windows phone is awesome
But obviously the poster who wishes to export text messages for legal reasons can disagree.
If that were a likely happenstance in the business I worked in, I would ensure all communication were carried out within a corporate account on a data-connection based messaging system.
This would be for multiple reasons:
1. Texts do text. This is rarely sufficient to cope with everything so therefore there are multiple communication paths required if files need to be transferred etc.
2. Data connections can ensure that the message is delivered, that you know it is delivered and that you even know they have seen it perhaps.
3. Data messaging systems allow multiple users in multiple groups with individual communications perhaps.
4. Data allows one to switch to any number of devices to continue the same conversation thread.
5. Backing up a data system is trivial, the server can do it as part of the overall system. Restoration is automatic and trivial.
6. Any number of suitable systems are available to run on anything and are free.
I am sure there are more reasons but the above seems sufficient to avoid a text-based system.
Obviously, I see no reason NOT to have an export mechanism, especially as the messages are stored on the OneDrive if enabled. Well, apart from the extra coding and testing etc. - the selection mechanism is already there after all, albeit only a basic one.
